The National Science Foundation Graduate Fellowship is awarded by the NSF to graduate students who show promise as leaders in their field.The program recognizes and supports outstanding graduate students in NSF-supported science, technology, engineering, and mathematics disciplines who are pursuing research-based master's and doctoral degrees at accredited United States institutions.
We discuss the design and implementation of thin film superconducting coplanar waveguide micro-resonators for pulsed ESR experiments. The performance of the resonators with P doped Si epilayer samples is compared to waveguide resonators under equivalent conditions. The high achievable filling factor even for small sized samples and the relatively high Q-factor result in a sensitivity that is superior to that of conventional waveguide resonators, in particular to spins close to the sample surface. The peak microwave power is on the order of a few microwatts, which is compatible with measurements at ultra low temperatures. We also discuss the effect of the nonuniform microwave magnetic field on the Hahn echo power dependence.

The NY Times has a write up about recent progress in superconducting quantum computing. My old group at Yale is featured as are the UCSB, and IBM groups. It's great to see broad interest in our work. (photo credit Erik Lucero)
Our recent paper demonstrating high cooperativity coupling between electron spins and a superconducting circuit has been attracting a lot of attention. Our work along with two other papers by Kubo, et. al. and Wu, et.
Professor Schuster was awarded the 2011 McMillan Award for pioneering contributions to the new field of "circuit quantum electrodynamics", particularly experiments coupling microwaves to spin ensembles and to superconducting qubits.
The DARPA Young Faculty Award (YFA) program identifies and engages rising research stars in junior faculty positions at U.S. academic institutions and introduces them to DoD needs and DARPA’s program development process. The YFA program provides funding, mentoring, and industry and Defense contacts to promising faculty early in their careers to help develop their research ideas in the context of Defense needs.
Professor Schuster receives NSF CAREER Award to study Hybrid Quantum systems using circuit quantum electrodynamics. The Faculty Early Career Development (CAREER) Program is a National Science Foundation-wide activity that offers the NSF's most prestigious awards in support of junior faculty who exemplify the role of teacher-scholars through outstanding research, excellent education and the integration of education and research within the context of the mission of their organizations.
Three professors from University of Chicago and the James Franck Institute faculty were selected as Sloan fellows.
The Alfred P. Sloan Foundation congratulates the winners of the 2012 Sloan Research Fellowships. These 126 early-career scholars represent the most promising scientific researchers working today.

We have engineered the band gap profile of transmon qubits by combining oxygen-doped Al for tunnel
junction electrodes and clean Al as quasiparticle traps to investigate energy relaxation due to quasiparticle
tunneling. The relaxation time T1 of the qubits is shown to be insensitive to this band gap engineering.
Operating at relatively low-EJ=EC makes the transmon transition frequency distinctly dependent on the
charge parity, allowing us to detect the quasiparticles tunneling across the qubit junction. Quasiparticle
kinetics have been studied by monitoring the frequency switching due to even-odd parity change in real
time. It shows the switching time is faster than 10us, indicating quasiparticle-induced relaxation has to
be reduced to achieve T1 much longer than 100us.
